ArrayList add方法(转)

由于 BrowerList 输出结果都是最后一条记录,后来网上查到了

                    if (dRead.HasRows)
                    {
　　　　　　　　　　　　　　List<Class_RejectQuery> BrowerList = new List<Class_RejectQuery>();
                        Class_RejectQuery listRow = new Class_RejectQuery();
                        while (dRead.Read())
                        {
                            listRow.id=dRead.GetString();
                            listRow.sn = dRead.GetInt32();
                            listRow.times = dRead.GetInt32();
                            listRow.cause = dRead.GetString();
                            listRow.auditor = dRead.GetString();
                            listRow.customer = dRead.GetString();
                            listRow.department = Convert.IsDBNull (dRead [])?"": dRead.GetString();
                            listRow.targetPerson = dRead.GetString();
                            listRow.recordName= Convert.IsDBNull (dRead[] ) ? "" : dRead.GetString();
                            listRow.auditDate = dRead.GetString();
                            BrowerList.Add(listRow);
                        }
                    }

仅仅是位置不同而已,结果却相大不相同

                     if (dRead.HasRows)
                     {
 　　　　　　　　　　　　　　List<Class_RejectQuery> BrowerList = new List<Class_RejectQuery>();
                                                  while (dRead.Read())
                         {
　　　　　　　　　　　　　　　　　　Class_RejectQuery listRow = new Class_RejectQuery();
                             listRow.id=dRead.GetString();
                             listRow.sn = dRead.GetInt32();
                             listRow.times = dRead.GetInt32();
                             listRow.cause = dRead.GetString();
                             listRow.auditor = dRead.GetString();
                             listRow.customer = dRead.GetString();
                             listRow.department = Convert.IsDBNull (dRead [])?"": dRead.GetString();
                             listRow.targetPerson = dRead.GetString();
                             listRow.recordName= Convert.IsDBNull (dRead[] ) ? "" : dRead.GetString();
                             listRow.auditDate = dRead.GetString();
                             BrowerList.Add(listRow);
                         }
                     }
